OK, I will give it a shot ...

There are more ways to set up a successful marine tank than there is a fresh water setup. I assume that you want to save cost, so I'd recommend a NATURAL setup rather than using all those expensive equiptments.

Your tank is a minimum recommended size for sake of stability. Any size smaller would require a more experienced hobbiest.

Wet/dry is NOT recommended for a marine tank ... it will give you short term success, but will crash your tank in the mid to long term.

Lots of people are using the DSB method ... stands for Deep Sand Bed. Try doing a search on the Internet and you will get tons of info. The very simplistic explanation is that with a sand bed with fine coral sand (about 1mm in diameter) for about 4-6 inches deep, your sand bed actually helps you filter the water!!! No kidding!!! I've been using it for about 3 years, and it works great!!!

Also, get live rocks to fill about 30-50% of your tank. The rocks ALSO helps filter the water.

Hopefully, you have an overflow filter system to the sump. Fill it up with bio rings (NOT bio balls!!!). Some people just grow macro algea in their sump to help filter the water.

Get the BIGGEST protein skimmer that you can afford.

You will also need a chiller to cool the water.

For the anemone to survive, you will need STRONG lighting!!!

Finally, put in LOT AND LOTS of water flow in your main tank.

Hope this helps!!!
